The University of Pittsburgh has withdrawn from debate tournaments held by the Cross Examination Debate Association as a result of an incident in which a Pittsburgh professor engaged in a profanity-laced argument with another professor, who mooned her. A video recording of the argument was posted on YouTube, raising questions about civility at college debate tournaments.

The incident took place in March at a national tournament of the debate association, when the coach for a team from Fort Hays State University, William Shanahan III, then a professor of communication at the Kansas institution, got into a shouting match with a judge, Shanara Reid-Brinkley, an assistant professor of communication at the University of Pittsburgh. At one point, Mr. Shanahan briefly dropped his pants and exposed his underwear, and both professors shouted profanities during the exchange.

Ms. Reid-Brinkley will not serve as a debate coach or a judge during any competitions this year, according to a statement issued today by the University of Pittsburgh, which says the professor’s behavior was “unacceptable” and in violation of its faculty code of conduct. The statement added that the university had suspended participation in tournaments held by the debate association.

Last month Fort Hays State fired Mr. Shanahan and suspended its debate team as a result of the incident.

Ms. Reid-Brinkley apologized for her behavior. “Despite serious provocation, such language was unprofessional,” she said in a written statement. The professor could not be reached for further comment.

The debate association has drafted a new code of ethical conduct for the organization, and has formed a committee to set standards for teaching debate at colleges. —Jeffrey R. Young
